The Sinclair Driver and Caseholder system is designed to hold and turn your case while you are neck turning,cleaning case necks or case mouth deburring. The Caseholders and Driver are machined from stainless steel, and the driver has a one fourth hex shaft for use in power screwdrivers or low-speed drill motors. The driver is universal to the Sinclair system and will work with all the Caseholders. Our universal Caseholder enables you to use this system for any cartridge case which has a Lee Auto Prime sheelholder available for it. The Universal Caseholder works with the same #05-2500 drivers as our original caseholders, and it is available as a kit with the Driver and Universal caseholder or individually for those who already have a driver. Remember to order a Lee Auto Prime shellholder for your Universal Caseholder if you don't already have one.

The Sinclair Driver and Caseholder system and a Sinclair Neck Turning Tool takes the hard work out of neck turning using either the Sinclair Power center or a power screwdriver. Holding the neck tuner in one hand and power screwdriver in the other negates the wobble in drive assembly of the screwdriver. This system is a great, inexpensive way to speed up the neck turning process. Also works great for many other case prep operations.
